Claude RTL Fix di Shahar Naor

Claude.ai does not set the correct text direction on message content, so Hebrew, Arabic, Farsi, and other right-to-left scripts render with broken alignment, misplaced punctuation, and reversed parentheticals. This extension fixes that.

How it works:

• Each block of text in a Claude message (paragraphs, list items, headings, blockquotes, table cells) is given the standard HTML attribute dir="auto", which lets the browser's built-in Unicode bidi algorithm pick the correct direction based on the first strong-directional character in the block.
• This handles mixed-language messages correctly. An English paragraph followed by a Hebrew paragraph followed by code will each render with the right direction, automatically.
• Code blocks (pre, code, kbd, samp, var) are explicitly forced to dir="ltr", so file paths, shell commands, and source code stay correctly oriented even inside an otherwise right-to-left message.
• A MutationObserver re-applies the fix as Claude streams new tokens in, so it works during live response generation, not just on already-rendered content.

Click the toolbar icon to toggle the extension on or off. The setting persists across page loads. When toggled off, all changes are reverted immediately without needing a reload.

Privacy: this extension does not collect, transmit, or store any data. It only reads the DOM of pages on claude.ai and adds standard HTML direction attributes. No network requests, no analytics, no telemetry.
